S922X - linux 6.18

[porschemad911]

Should probably wait for 6.18 to go final, just experimenting with 6.18 RC versions in the meantime.

kconfig updated via olddefconfig, megi/linux rk817 and rk818 patches rebased, other patches applied cleanly. Everything builds fine.

Testing:

• display
• audio
• controls
• wifi
• bluetooth
• USB ethernet
• libmali
• panfrost

Tested on my OGU as a daily driver, everything working fine.

TODO - had to temporarily remove strace from build, need to wait for a 6.18-compatible version.

bumping u-boot/tfa (if possible) might solve the cpu parking/unparking issue

Thanks I'll take a look. Park seems fine, hard reboot on unpark. I can't catch logs but probably a kernel panic.

@loki666 After a lot more trouble-shooting, it is actually the weston-kiosk-shell-dpms package dpms-client -m on command that is hard-rebooting the system (with both panfrost and libmali), the core parking is fine.

Some newer commits here: https://github.com/akhilharihar/Weston-kiosk-shell-DPMS

Will rebase build patch and test.

Update - switched to controlling backlight via sysfs instead which works fine and avoids the hard reboots.
